Forensics Design Of Intelligence Terminal System Based On Android

With the rapid development of science and technology information has become an important resource on people’s work and life. Meanwhile, mobile communications technology as the representative of information technology bring great convenience to people’s work and life. Such the phenomenon also inevitably leads to a variety of negative issues. For instance, the use of Internet fraud, illegal online trading, online spies, hackepattacks, online spying and other crimes emerge, showing a rapid growth momentum The use of a smart phone or other wireless mobile devices to carry out criminal is a typical high-tech crime, urgent needing to design appropriate measures to prevent, monitor and fight to ensure sustained and rapid development of information technology. The challenge of using the information technology for fighting crime is how to implement the crime in accordance with laws and regulations to identify facts of the crime and convert the key facts of the crime to obtained valid evidence. Given the increasingly wide-spread use of Android-based wireless mobile terminal equipment, the needs of extraction, processing and analysis the data in the smart terminal equipment become more urgent. Public security organization, courts and other law enforcement agencies at all levels need to get address book, call history, SMS recording, digital photos, documents and other types of information in the smart equipments of the involved, to recovery the deleted information as far as possible, to facilitate investigations and trials.Based on the relevant characteristics of smart phones this thesis design a new algorithm of fast non-volatile data storage media recovery recovering the data deleted from the smart phone, devise a lightweight phone module, monitoring mobile phone short messaging, telephone answering and call events, system information for extracting and back up. On this basis, design a forensic platform for mobile phones inside the extraction of relevant information, the forensic system software tamper proofing. Embed digital signatures after extraction of the files, to ensure the effectiveness of forensics and inform forensics personnel the path of forensic report, to get the final data.
